ASELF-CLOSING STRAlNlNG-FAUCET.

SPECIFICATION forming part of Letters Patent No. 587,416, dated August3, 1897.

Application led Maoll 23, 1895. Serial No. 542,979. (N model.)

To @ZZ whom t may concern,.-

Be it known that I, THOMAS P. WHITEHEAD, a citizen of the United States.residing at Shreveport, in the parish of Caddo and State ot' Louisiana,have invented a new and useful Self-Olosin g Straining and Non-FreezableFaucet, of which the following is a specification.

The present invention aims to provide an ro vimprovement in faucets ofthat type used for cisterns, tanks, and caslis and which will strain theliquid drawn oft and at the same time be self-closing and provideagainst freezing.

The invention primarily contemplates the provision of a swinging bailadapted to engage with the outer end of the valve-stem and retain thesame against the action of its spring, so as to hold the valve unseatedwhen 2o it is required to draw off a large quantity of fluid, said bailbeing provided with a stop to limit its downward movement and preventaccidental displacement when in operative relation.

The improvement consists of the novel features and the peculiarconstruction and combination of the parts which hereinafter will be morefully described and claimed and which are shown in the accompanyingdrawings, in which- Figure 1 is a perspective view of a faucetconstructed in accordance with and embodying the essence of theinvention. Fig. 2 is a central longitudinal section of the faucet,

3 5 showing the relative disposition of the parts when the valve isunseated and the bail is in engagement with the outer end of thevalvestem. Fig. 3 is a view similar to Fig. 2, showing the location ofthe parts when the valve 4o is seated, the bail being thrown back out ofthe way. Fig. 4 is a detail View of the swinging bail. Fig. 5 is adetail view of the valve.

The numeral l represents the body of the faucet, which tapers in lengthandis of circular contour in cross-section. The body is closed at itsouter end and open at the inner end and is provided with a longitudinalbore 2 for the passage of the liquid therethrough. A lateral spout 3,near the outer end of the 5o body, communicates with the bore 2 and ispreferably threaded on its outer end to form connection therewith of ahose-or otherpipe, by means of which the fluid may be conveyed to thedesired point of discharge. A valveseat ais formed at the inner end ofthe body land flares outwardly from the walls of the passage 2 andintersects with the outer surface of the body, so as to form asharpscraping edge 5 for the purpose of removing any matter that may cling tothe inner sides of the 6o strainer 6. The valve-stem 7 passes looselythrough the bore 2 and has the valve 8 attached to its inner end and anoperating-button 9 to its outer end. The outer portion of the valve-stemis threaded, and a tension-nut l10 is mounted thereon and is designed tocompress a coil-spring l1 more'or less to vary the pressure with whichthe valve 8 is held upon its seat. A small recess or bore l2 extendsinward from the outer end of the body 7o 1 to form a housing for thecoil-spring 11 and prevent tampering therewith or the clogging of thesame by foreign matter. A washer 13 is loosely mounted upon the outerportion of the valve-stem 7 and obtains a seat upon the 75 inner end ofthe recess 12 to prevent injurious contact of the inner end of thespring 11 with the inner end of the said recess 12.

The strainer 6 is cylindrical in form and is adapted to lit snugly uponthe inner end of 8o the faucet-body 1, but not so tightly as tointerfere with its free movement thereon. This straineris constructed offoraminous sheet metal, which is wired at its front end to ob- Viateinjurious contact with the faucet-body and is closed at its rear end,which closed end is centrally apertured to receive the projectingthreaded end of the valve-stem 7, upon which is mounted a clamp-nut 14,by means of which the said strainer is held in place. A 9c smallcircular plate 15 is firmly attached to the inner end portion of thevalve-stem and forms a stop to sustain the valve 8 and the closed end ofthe strainer 6 against the pressure of the clamp-nut 14E. The valve 8 is95 conical shaped and is preferably formed of rubber and when closedobtains a close iit upon its seat 4.

The bail 16 has pivotal connection with the sides of the faucet-body andis adapted to Ioo swing in a vertical plane and has an inwardlyextendingflange 17, which forms a stop to engage with the button 9 on the outerend of the valve-stem and limit the downward movement of the said bailand prevent accidental disengagement thereof from the button whenrequired to perform service. This bail is constructed from sheet metal,which is bent substantially in the form shown and has openings in theends of its members to receive screws or other fastenings 18, by meansof which it is pivotally attached to the faucetbody.

By having the bail constructed of sheet or similar light metal its sidemembers can be spread or brought together, thereby adapting the bail foruse with different-sized faucets, and the manner of pivotally connectingthe bail with the faucet admits of the pivots being properly located, sothat the closed end of the bail will engage with the button 9 or end ofthe valve-stem after the latter' has been pressed inward to unseat thevalve.

From what has been said it will be seen that the faucet is constructedwith special reference to have its parts protected and also obviatechoking or clogging of the strainer, while at the same time the latterserves to guide the valve to its seat and is itself cleared from allforeign matter by means of the scraping edge 5 at the inner end of thefaucetbody. When it is required to leave the faucet open, the button 9is pressed in and the bail 16 is turned down until its closed endextends over the said button, when the latter will be held against thetension of the spring 11 by means of the said bail, as will be readilyunderstood.

It must be remembered that the bore or passage 2 of the faucet-body isconsiderably larger than the valve-stein 7, so as to provide for a freeflow of the liquid when the valve is unseated. Hence the advantage ofthe provision of the strainer 6 to serve as a guide and support for theinner end of the valvestem is manifest. In the reciprocatory movementsof the valve-stem the valve 8 is moved to and from its seat without anysliding action, which would be the case if the strainer G were dispensedwith, as in this event the valve when unseated would sag or get out ofline and when seating would slide upon its seat to effect a closure. Theprovision of the strainer serves both to support the inner end of thevalve-stein and as a means to separate the iuid from impure matter ofsufficient bulk to prevent its passage through the per- `forations ofthe metal from which the strainer is constructed.

Having thus described the invention, what is claimed as new is- Thecombination with a faucet-body provided at its inner end with avalve-seat, and a spring-actuated valve-stem carrying at its inner end avalve and at its outer end beyond one end of the faucet-body anoperating-button, of a U-shaped bail made of a single narrow strip oflight sheet metal and comprising opposite side members and a cross-piececonnecting the side members at one end, the cross-piece being Wider thanthe side members and bent at one edge to produce an integralright-angularly-disposed flange 17 adapted to engage over the top edgeof the button, and the side members of the bail embracing the oppositesides of the faucet-body and having pivotal connection therewith in linewith the valve-stem to admit of the bail being thrown back upon thefaucet-body entirely out of the way when not in use, substantially asset forth.

In testimony that I claim the foregoing as my own I have hereto aiixedmy signature in the presence of two witnesses.
